Integrate acts_as_rated plugin in rails application

I am creating a user-boards applicationin rails in which a user owns any number of boards and can rate the boards.I want to install acts_as_rated plugin in my rails application. Since this is not available as a gem i have used following command to install it as a plugin:

rails plugin install svn://rubyforge.org/var/svn/acts-as-rated/trunk/acts_as_rated

This command installs all required plugin files in the vendor directory. Next I include the following code in my Boards model

class Board < ActiveRecord::Base
  acts_as_rated
end

Next i restart my console and run the following commands

u=User.first
 => #<User id: 1, first_name: "taroon", created_at: "2012-03-26 09:18:20", updated_at: "2012-03-26 09:18:20">

b=Board.first
 => #<Board id: 1, name: "boards_1", created_at: "2012-03-26 09:19:39", updated_at: "2012-03-26 09:19:39"> 

b.rate 5, u

It gives me the following error

ActiveRecord::StatementInvalid: Could not find table 'ratings'

I checked out the migartion but no migration for rating tables was created. Neither I have an idea of the fields in this table.

Can anyone please suggest me a solution for this problem..

Solution

The README of act_as_rated plugin says that you need to do your own migration based on this file: test/fixtures/migrations/001_add_rating_tables.rb.

Quote from the README:

The file test/fixtures/migrations/001_add_rating_tables.rb shows examples of all types of migration options.

See also the detailed documentation for the acts_as_rated method on how to declare it, and the rest of the documentation for how to generate the migration columns/files and how to use it.

So download and extract your module from here, then you can find the corresponding file and you can do your own migration.
